Had the same problem on a 68 once. Got a locking gas cap and it solved it. The locking cap seems to let the vapors escape better...just a thought

I agree, A bad gas cap can definately cause vapor lock. Back in the 80's, I had a 77 Ford with the tank behind the seat and it would vapor lock on the freeway all the time. Used to reach out the window and pull out on the cap to release the pressure. Too lazy to buy a new cap back then.

I have a locking gas cap on my 69
